Sport fish have declined significantly in portions of the Upper Mississippi River infested with Asian carp, adding evidence to fears about the invader's threat to native species, according to a new study.

Women who are diagnosed with peripartum cardiomyopathy (PPCM) during late pregnancy or within a month following delivery are more likely to experience restored cardiac function and improved outcomes compared to those who are diagnosed later in the postpartum period, according to a new study from Penn Medicine.
